How to prune the sycamore, the specific method of the French sycamore cuttings

French sycamore, scientific name plane tree. It is a deciduous tree.

Pruning is generally in late winter and early spring. Keep the main side branches, and cut off the upright branches and overly long side branches.

1. Cuttings are stored and stored. Before the Spring Festival, the cellar will be dug 50 cm deep, watered thoroughly with water, until the water is exhausted, no clear water, then the bundled seed strips back to the buds are arranged neatly downward, and the seed strips are sprinkled densely between the cracks with broken soil, and the seed strips can be arranged in two layers, and the top layer can be pressed about 15 cm with broken soil.

2. Cutting method. Insert the stored tung tree, that is, the sycamore, into the mulched land before and after, with a plant spacing of 30 cm and a row spacing of 60 cm. Cuttings must be inserted straight and the top bud is close to the mulch.

When cuttings, the mulch film must be inserted first, and then the cuttings, in case the embryo is difficult to generate, resulting in difficulty in taking root.

3. Watering time. After the cuttings of the French plane tree, it should be watered immediately, and when the soil is suitable, find the cuttings in time to keep the upper bud above the mulch. When the second water is poured after the inspection, pesticide 3911 should be used and applied with the watering.

Watering 7 to 8 times a year.

1. Sowing methodTung sowing is generally sown. Before planting, the soil is watered and then the seeds are scattered along with fine sand. The line spacing between each strip needs to be 20cm, and it is spread evenly.

Sprinkle about 3 cm of soil and spread a layer of straw. After the seedlings emerge, transplantation, each plant is 2m apart is appropriate.

2. Tending and maintenanceAfter the seeds are sown, it is necessary to do a good job in seedling management, such as irrigation, top dressing, weeding and loosening soil, etc., and top dressing should be done in small quantities and many times at the seedling stage. In addition, in the rainy season, it is necessary to drain water in time to prevent root rot, and it is also necessary to pay attention to the transplantation of seedlings in rainy days, and check the growth of seedlings frequently.

French sycamore seedling breeding method:

1. Seed collection: When collecting seeds, choose to collect from mature trees with fast growth, straight stem shape and good development. Before sowing, it can be sown at the same time, or after the seeds are ripe, pick up large fruits on the ground for seeding.

After the fruit is harvested, it is dried and smashed open with bricks or wooden sticks to reveal small, cone-shaped nuts with long yellow-brown hairs. After rubbing, remove the hair, that is, get a net seed. Then, put it in a bag for storage.

When handling seeds, wear a mask and pay attention to hygiene.

2. Germination: In order to make the seeds germinate quickly, emerge and grow strong after sowing, germination should be carried out before sowing. The method is to shoot the hole stove:

30-40 degrees Celsius wet water, soak the seeds for 10 minutes, add cold water for 1-2 days, take out and put it into the pouch, put it in a place of 20-30 degrees Celsius, maintain the seed humidity for germination, after 5-7 days, when the seed radicle is slightly dark, you can sow seeds.

3. Sowing method: sowing time, generally in late April. In recent years, observations have shown that sowing before the rainy season is more effective.

Because after sowing, it is the season of more rain, high humidity and high temperature, so the seeds germinate quickly, the seedlings emerge together, and the management is labor-saving. Sowing method: There are two kinds of sowing methods: spreading and stripping.

The row spacing of the strip is 20-25 cm. After sowing, the thickness of the covering soil should be slightly seen. At the same time as sowing seeds, they are sprinkled with poison valley to kill underground pests.

When sowing seeds on clay soil, it is often covered with a layer of straw after covering the soil in order to preserve moisture and prevent surface compaction, which is better, but it is necessary to prevent and control underground pests in time.

4. Tending management: Before and after the seedlings are unearthed, the surface is often kept moist, which is the key to the success or failure of sowing and raising seedlings. raised beds for seedlings, irrigated sideways; When raising seedlings in flat beds, irrigate with "trembling letter water and small water", generally once every 3-4 days.

After irrigation, the seedbed should not accumulate too much water, so as not to be too humid, causing the seedlings to rot their roots and causing death. The height of the seedlings is about 5 cm, and the seedlings are thinned, and the seedlings are set at about 10 cm, and the plant spacing is 15-20 cm. During the seedling period, weeding is the mainstay, and generally no tillage is carried out, and the topsoil can be loosened with a hand rake, which is conducive to the growth and development of seedlings.

In order to ensure the yield and quality of seedlings, the seedling stage should be timely controlled underground pests and bag moths.

5. Seedling selection: French plane seedlings, serious differentiation. In order to achieve fast growth after planting, early timber and beautiful tree shape, it is necessary to select excellent and strong seedlings from the seedlings and eliminate the bad seedlings.

Experience shows that strong seedlings with fast growth, long internodes, large leaves, and no infection with leaf spot or very mild infection should be selected; The seedlings with slow growth, short internodes, reddish-brown dry skin, small leaves, deep lobes, and serious diseases will be eliminated.

Injection method: Generally, a hole with a diameter of about 5 mm is drilled in the trunk 50 cm above the ground, and the injection is 4-5 cm deep, and the "catheter" in the trunk is directly transmitted to the branches and leaves. "The agent has no *** for the growth and development of tung trees.

There are dozens of agents that can interfere with hormones in plants, and these two types are selected through experiments. Director Su said that this success made the researchers in charge of this project very excited, but it could not be promoted on a large scale for the time being. It turned out that the specifications, resistance, and crown width of each plant were different, and the dosage was still being explored.

The fruit flies on the sycamore tree are flying around and making people's eyes and nostrils itchy and uncomfortable, and if we want to make it sterile, we should ask experts in this area to solve it.

The fruit flocs of the sycamore fly everywhere, making people's eyes and nostrils very itchy and difficult, and if you want to sterilize it and not bear fruit, you must ask experts in this area to solve it.

Cuttings of two-year-old branches, watering more.

In winter, prune the branches of the current year, leave about 3 buds and nail them into the soil to sprout in the next year.

The French plane tree blooms, the flowering period is from April to May, the head inflorescence is spherical, the spherical inflorescence is centimeter in diameter, usually 2 in a bunch, in the shape of a hanging bell; The flowers are about 4 mm long; sepals 4; petal 4; Staminate flower; Male flowers have 4-8 stamens; Female flowers have 6 isolated carpels.

French Plane Tree Habits:

Hi-light. It prefers humid and warm climates and is more cold-tolerant. It is suitable for growing in slightly acidic or neutral, well-drained soil, although slightly alkaline soil can grow, but it is prone to yellowing.

The root distribution is shallow, and it is susceptible to damage and tilt during typhoons. It has strong resistance to air pollution, and the blades have the effect of absorbing toxic gases and stagnant dust. This species has a tall trunk, lush branches and leaves, rapid growth, easy to survive, and resistant to pruning, so it is widely planted as a street greening tree species, and it is also a fast-growing timber tree species; It has strong resistance to toxic gases such as Ryu dioxide and chlorine.

There are three genera of plane trees, namely one-ball plane tree, two-ball plane tree and three-ball plane tree. The common names are American Sycamore, English Sycamore, and French Sycamore, respectively. (Sycamore, also known as plane tree).

Native to Europe; It is also found in India and Asia Minor.

Sycamore trees bloom. The flowering season is June.

The leaves are palmately 3 5-lobed, the lobes are entire, the base is heart-shaped, and the petioles are elongated. Flowers unisexual or heterogeneous, apical conical inflorescences, flowers small, yellowish-green, without petals, capsule fruit-like, dehiscent before ripening, petals leaf-like, seeds spherical, bearing on the edge of the petals. The flowering period is June, and the fruit is ripe in September.

The three-ball plane is up to 30 meters tall and has dark gray bark with flaking flakes and greenish-white inner skin. The shoots are covered with yellowish-brown stellate hairs. The leaves are 8 to 16 cm long, 9 to 18 cm wide, 5 to 7 deeply lobed to middle or below, the lobes are narrow and long, and are covered with grayish-yellow stellate hairs when young, and then shed.

The stalk is spherical, 2 to 2 5 cm in diameter, the columella is 3 to 4 mm long. The flowering period is May, and the fruiting period is from September to October.

The two-ball plane is a hybrid of the three-ball plane and the one-ball plane tree, and was bred in London, England. Up to 35 meters high, the bark is peeled off and the inner bark is pale greenish-white. The young branches and leaves are densely covered with light brownish-yellow stellate hairs.

Leaves 10 to 24 cm long, 12 to 25 cm wide, base truncated or slightly heart-shaped, 3 to 5 deeply lobed, middle lobes nearly equal in length and width, entirety or sparsely toothed. The inflorescence is about 2 5 cm in diameter, the columella is 2 to 3 mm long, and the spines are thorny. The flowering period is from April to May, and the fruiting period is from September to October.

The plane tree is 40 meters high, the leaves are 3-5 shallowly lobed, the width is greater than the length, the lobes are broadly triangular, and the cones are mostly solitary and without prickly hairs.
